ETA on moving new API functions in HEAD to 4.7?

I'm working on a module called Community Tags based off RobRoy's fine work with Tagadelic module. I saw all these kick-butt API functions like tagadelic_build_weighted_tags which allowed me to write a theme function that was just:

function theme_community_tags_node($nid) {
  $result = db_query("big fancy query", $nid);
  $weighted_tags = tagadelic_build_weighted_tags($result);
  $sorted_tags = tagadelic_sort_tags($weighted_tags);
  return theme('tagadelic_weighted', $sorted_tags);
}

The problem? Those fancy functions are only in the HEAD version of Tagadelic. :( And I imagine any day now that might turn into the 5.0 version which will horribly break 4.7 sites, so I'd rather not deploy it. ;)

Do you need help testing, or is there anything else I can do to help this along?
